L293D Datasheet

The L293D datasheet specifies that this device is a monolithic integrated high voltage, high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays solenoides, DC and stepping motors) and switching power transistors.

This device is suitable for use in switching applications at frequencies up to 5 kHz. The L293D is assembled in a 16 lead plastic packaage which has 4 center pins connected together and used for heatsinking. The L293DD is assembled in a 20 lead surface mount which has 8 center pins connected together and used for heatsinking.

L293D Features

  • 600mA output current capability per channel
  • 1.2A peak output current per channel
  • enable facility
  • overtemperature protection
  • logical “0” input voltage up to 1.5V (high noise immunity)
  • internal clamp diodes
